HASP-LOCK.

SPECIFICATION forming part of Letters Patent No. 393,163, dated November20, 1888.

Application filed April 16, 1888. Serial No. 270,791. (No model.)

T0 ,aZZ whom it may concern.-

Be it known that 1, CHARLES E. LEE, 2. citizen of the United States, anda resident of Allegheny, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inHasp-Locks; and I do hereby declare that the following is a full, clear,

and exact description of the invention, which ing parts in the severalfigures.

Myinvention has relation to devices for look ing the hasp of atrunk-lid, the cover of a box or crate, or other receptacles upon thestaple, and has for its object to lock the hasp and the staple togetherin a manner which, while both secure and expeditious, yet permits thehasp to be locked or unlocked in a few moments. At the same time theobject ofv my invention is to construct a device which shall beinexpensive and yet sufficiently strong and durable to resist the wearand tear of shippingcrates, egg-boxes, &c.

Reference being had to the accompanying drawings, the letter A denotesthe hasp, which is fastened to the lid of the box or crate (shown at B)by the usual hinge and hinge-leaf, Gand D, and provided with the usuallongitudinal slot, E, adapted to fit over and receive the staple F.

The lock or locking device consists of a seg ment, G, of iron, steel, orother suitable material, which is provided with a concentric slot, H, soas to form a circular hook, I, the pivot of which is formed by a pin orrivet, J,which is fastened in the hasp above the slot E and in a linewith the said slot, and upon which the segment turns freely.

One end of the segment, at a short distance from the inner end of theslot H, is turned up at right angles to form a thumb-piece orprojection, K, whereby the segment may be readily turned upon its pivotJ for looking or unlocking it.

The operation of this device will readily be understood by reference tothe drawings without requiring extended explanation. It will. be seenthat when the segment is in the position denoted in Fig. 2-that is tosay, when the point of the curved hook I is clear from the staple-thehasp may readily be withdrawn from the latter, so as to open the box orcrate, and when the locking-segment is in this position it will also beseen that the thumb piece or projection K, by abutting against thestaple, forms a stop or abutment, which prevents the segment from beingturned too far. When, on

the other hand, the segment is swung back into the position shown inFig. 1, the circular hook will enter the staple and engage the same, sothat the hasp cannot be withdrawn. Thelooking-segment will remain inthis closed position of its own accord, owing to the gravity of theprojection K and the adjacent slotted part of the segment,.whichoperates to keep the de vice in the locked position shown in Fig. 1.

Havingthus described my invention, I claim and desire to secure byLetters Patent of the United States- The combination, with a hasp, ofthe looking device herein described, the same consisting of a segmenthaving a circular hook and corresponding concentric slot and providednear the inner or closed end of said slot with a raised projection orthumb-piece, substantially as and for thepurpose herein shown and setforth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

CHARLES E. LEE.
